"As usual, it's all been misreported," she recently told Ryan Seacrest on his KIIS-FM radio show. "No, my husband has not spilled the beans."

Explains James: "What happened is that his local paper ... reported on my husband being the inspiration for Christian Grey," she tells Seacrest. "Underneath it, they put a picture of Ryan Gosling as well. So, that's how that [rumor] came about."

James, meanwhile, says she may or may not have someone in mind for the steamy role, but declines to name any names. Why? "[It's] far too early in the process," she says.

Seacrest also played clips of past interviews he's conducted with actors who may be in contention for the role of Christian. Among the clips he played were interviews with Jake Gyllenhaal, Chris Pine and Ian Somerhalder.

At the end of the day, James tells Seacrest that the whole experience of writing the popular books has been wild. "I wasn't prepared for all this [attention]," she says. "This whole roller coaster has been completely mind-blowing."
